The ọkara adabara chemical usoro nfuli bụ isi corrosive, na maka nkewa nke corrosion, e nwere n'ozuzu abụọ nhazi usoro.

A na-ekewa usoro ahụ, nke ọzọ bụ nkewa dịka ihe kpatara na ọdịdị nke corrosion si dị. Dị ka usoro nke corrosion si dị, ọ nwere ike kewaa ya na electrochemical corrosion na chemical corrosion. Electrochemical corrosion tumadi na-ezo aka na onu nke corrosion nke electrode mmeghachi omume n'elu nke metal ihe mgbe ọ batara na kọntaktị na electrolyte ngwọta. Mmeghachi omume a n'ozuzu bụ mmeghachi omume redox, na isi ihe bụ iru mmiri na okpomọkụ nke gburugburu ebe obibi; Nbibi kemịkalụ na-ezo aka na mmeghachi omume kemịkalụ siri ike dị n'etiti elu igwe na ihe ndị gbara ya gburugburu, nke na-eme ka ígwè ahụ mebie ruo n'ókè ụfọdụ. Isi ihe kpatara mmebi a bụ oke okpomọkụ na ebe akọrọ. Dị ka ọdịdị na akpata corrosion si dị, ọ nwere ike kewaa n'ime peeling corrosion, ụlọ ọrụ ikuku corrosion, elu okpomọkụ oxidation corrosion na mmiri ikuku corrosion.

Na gburugburu ebe obibi nwere mmetọ ụlọ ọrụ siri ike, n'ihi na enwere ihe ndị ọzọ na-agbanwe agbanwe dị ka sulfide, carbon dioxide na hydroxide na ikuku, yana nwekwara ụfọdụ uzuzu ụlọ ọrụ, ndị a bụ mgbasa ozi dị mfe ime ka corrosion. Mgbe mgbasa ozi ndị a nọ na gburugburu iru mmiri, gas acid ga-ejikọta ya na mmiri iji mepụta acid inorganic. Acids ndị a nwere ihe ndị na-emebi emebi siri ike, yabụ na ha ga-ebute corrosion. Na gburugburu ebe obibi nke ụlọ ọrụ mmepụta ihe, akụrụngwa na-akpata site na ngwakọta nke corrosion electrochemical na corrosion kemịkalụ kpọmkwem. Ihe kachasị mkpa nke corrosion niile bụ usoro oxidation nke metal ọcha na-atụfu electrons iji mepụta ion. Isi ihe dị iche n'etiti electrochemical corrosion na ụlọ ọrụ ikuku corrosion bụ gburugburu dị iche iche nke ha na-eme.

Nchicha nke akụrụngwa nwere njikọ chiri anya na ihe akụrụngwa. N'ime usoro nhọrọ nke ihe ndị na-emepụta ihe, anyị kwesịrị ilekwasị anya na ihe omume nke corrosion, ṅaa ntị na nhọrọ ezi uche dị na ya, ma chee echiche nke ọma na njirimara nke ọkara, okpomọkụ nke gburugburu ebe obibi na nrụgide ọrụ, wdg. ụlọ ọrụ kemịkalụ Ihe achọrọ nke akụrụngwa na nhazi na ụdị akụrụngwa akụrụngwa. Nhazi nke ihe owuwu ahụ kwesịrị ilekwasị anya na mmepụta chọrọ na njirimara nrụgide na mmepụta na ịrụ ọrụ nke akụrụngwa kemịkalụ, na akụkụ ndị a kwesịrị ịṅa ntị na nhazi ahụ: nke mbụ, ihe ndị a chọrọ n'usoro nke ngwaahịa kwesịrị ịdị na corrosion. Nguzogide chọrọ nke mmepụta nke ngwaahịa kemịkal; Nke abuo Ọ dị mkpa ịṅa ntị na nkwụsi ike na-arụ ọrụ na ire ụtọ nke ngwá ọrụ kemịkal, iji gbochie nkwụsị nke mgbasa ozi na-emebi emebi, nkesa na-adịghị mma nke ibu ọkụ, ikuku nke uzuoku na nchịkọta nke ngwaahịa corrosion; N'ikpeazụ, ọ dị mkpa ịṅa ntị na nchebe nke ndị agha dị n'èzí iji gbochie ike ọgwụgwụ nke ike ọgwụgwụ na-akpata site na nrụgide ọzọ.
